CRESS

Backfeed and Additional Demand

Referring to Clause 7.6 of the CRESS Guidelines, which outlines that "The RED shall also enter into Backfeed Agreement with the EUC to obtain electricity supply for the plant's own consumption, backfeed requirement during construction, and other and other usages". i. Will there be restrictions in the Backfeed Agreement (or otherwise) to prevent a BESS from charging from the grid? ii. If so, what nature will these restrictions be? iii. Would the Backfeed Agreement be similar to the Electricity Supply Agreement TNB has with large power consumers, or in a reduced and simplified form?

Application and Qualifications

What is the definition of new customer? Customer has signed the ESA, and the supply is given before the CRESS effective date. Customer declared the staggered Maximum Demand as below. Can customer join CRESS for the additional staggered load for the coming years? Eg, Customer final MD is 100MW with staggered load declaration. Year 1 = 10 MW (current year) Year 5 = 50 MW Year 15 = 100MW (final load). Customers have signed ESA and supply is given before effective date of CRESS. Can customers close their account and submit new supply application to join CRESS under the new account? When can a CRESS application be submitted? Customers have signed ESA but supply not yet given on the effective date of CRESS. Can customers join CRESS?

System Access Charges (SAC) and Regulatory Framework

With reference to section 6.20, where the MRED is greater than the total MGC due to the Green Consumer’s lower energy usage, the amount of energy greater than the MGC shall be deemed as free energy. Do the RECs in this instance belong to the RED, as the RED is not being compensated through NEDA for the output injection into the grid? Further, will this output be registered in MRED? With reference to section 8.12, where the exported energy of RED is greater than the maximum monthly energy demand by the Green Consumer due to an imbalance between generation and demand, such exported energy will not be compensated. In this instance, do the RECs belong to the RED? Since the RED is not being compensated through NEDA for the output injection into the grid? Further, will this output be registered in MRED? With reference to section 8.14 (a) and (b), what would be the price difference in the System Access Charge (SAC) for a Green Energy Plant (GEP) with and without a BESS? In section 11, it is stated that “SAC shall be reviewed in every Regulatory Period”. What is the definition of “Regulatory Period,” and is there an assumption of how volatile the SAC will change (if any).
